我的蓝牙耳机有大约 200 毫秒的延迟。在 VLC 上，我可以通过手动设置音频同步加速来纠正此问题，但在 Chrome 上（例如观看 Youtube 时）我看不到任何调整方法。是否有可能，或者实际上不可能通过蓝牙同步在 Chrome 上观看 Youtube？
直到我在 grub 上按回车键，我的系统才会启动。
cat /etc/default/grub

为什么GRUB_TIMEOUT设置不起作用？我运行了update-grubGrub Customizer，但没有任何帮助。我os-prober的也不行。他们都在我使用 14.04 时工作，现在我使用的是 14.10。
自升级到 14.04 以来，我在 apt-get 更新方面遇到了一些问题。它总是以报告配置某些包的错误告终。这是看起来相关的日志：

我有一个 MP3 播放器，它删除了大部分文件。我立即使用 dd 创建了一个 8GB 的图像文件。
我查看并尝试使用一些恢复软件，但它们只是给了我一堆文件，通常未命名并且不在树中的正确位置。其中一些不适用于图像文件。我可以使用哪些程序来恢复已删除的文件，以便将它们直接复制到驱动器？
